The Queen wore pink for Day 1, which is always good, but even more thrilling is the fact that she debuted a brand-new brooch! And even better? It's a major British heirloom. The Crown Ruby Brooch originally belonged to Queen Victoria; it was set with opals instead of these enormous rubies when it was made by Garrard in the 1850s. The brooch was later altered, and the opals were replaced. It was worn by Queen Mary, and then by the Queen Mum. Today was the Queen's first-ever public appearance in this important brooch. So exciting!

No real jewel surprises, however, from the Duchess of Cornwall, who wore her standard pearl and diamond jewelry. The neckline of her dress, however, also gave us a glimpse of the small pendant she wears underneath her larger necklaces. (The hat? The minty cornhusks need to go.)

Sophie Wessex was the picture of elegance, as per usual, but she also didn't offer any jewel surprises, wearing the same pearl cluster earrings and brooch that she's been sporting frequently over the past few weeks.

Lady Sarah Chatto was also in bold black and white colors, wearing earrings that belonged to her late mother, Princess Margaret. (I think the brooch may also be one of Margaret's, but I can't be sure from this angle.) But the bigger question: is that a real camera or a fancy purse?

One more customary royal guest stopped by for the first day: Princess Haya of Jordan, wife of the Sheikh of Dubai. Love the small pearl earrings, totally perplexed by the hat. There is such a thing as too many flowers.
